Detailed Description

For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. The components of the embodiments of the present application, which are generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the present application, as provided in the accompanying drawings, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

In the description of the present application, it should be noted that terms such as "top surface" and "bottom surface" are used to refer to the top surface of the side of the rotary apparatus operating status signal monitor of the present application that faces upward in the use state, and the bottom surface of the side that faces downward; the use of terms such as "first" and "second" is for the purpose of distinguishing between similar elements and not necessarily for the purpose of indicating or implying any particular importance or order of such elements; terms such as "inner", "outer" and "inner and outer" are used to refer to specific contours. The above terms are used only for the sake of clarity and simply to describe the technical solutions of the present application, and should not be construed as limiting the present application.

First, in order to facilitate a clearer understanding of the technical solutions of the present application by the related art, the following detailed description is provided for the technical problems existing in the related art.

As for the first problem mentioned in the background art (i.e., the problem of inconvenient installation of the vibration sensor), since the rotation device and the vibration sensor are separately designed, manufactured and sold by different manufacturers, the rotation device generally does not reserve an installation structure (e.g., a bolt hole, a stud, or a welding area) of the vibration sensor. At present, the installation mode of the vibration sensor generally comprises two types, namely, a threaded connection structure is adopted, namely, the installation is realized through a protruding stud (corresponding to one welded if no stud exists) on the rotating equipment by utilizing a threaded hole formed in the bottom of the vibration sensor, or the installation is realized through a threaded hole (corresponding to one opened or butted through another threaded structure if no stud exists) on the rotating equipment by utilizing a stud formed in the bottom of the vibration sensor. And secondly, the vibration sensor is welded to an arc plate (attached to the shell of the rotating equipment) firstly, and then the arc plate is welded to the shell of the rotating equipment, so that the close attachment is realized. Thus, the welding of studs or the provision of threaded holes in the housing of the rotary device may have an effect on the structure of the rotary device, even if the structure of the rotary device is destroyed, and it is a difficult problem how to disassemble the rotary device after the rotary device is mounted by means of welding.

For the second problem mentioned in the background art (namely, the casing of the rotating device is generally an arc surface, and the mounting and attaching performance of the vibration sensor is poor), since the casing of the rotating device is generally a columnar or cylindrical structure and has a large number of arc surface areas, and various other devices or structures (such as an output device, a power supply structure, a speed regulating device and the like) are generally arranged at two ends of the rotating device, the mounting space of the vibration sensor is limited, and the vibration sensor can be generally only mounted on the arc surface of the rotating device, while the bottom of the conventional vibration sensor is generally a relatively gentle structure, so that the attaching performance with the arc surface is poor, the mounting is inconvenient, and the mounting and attaching adaptability is poor.

In view of the foregoing, the present application provides a completely new rotary device operation status signal monitor to at least partially solve the above-mentioned technical problems.

The following describes the technical scheme of the present application in detail with reference to the accompanying drawings.

Example 1

It should be understood that the detachable connection manner of the vibration sensor 1 and the base 2 in the present application has various embodiments, for example, in an exemplary embodiment, as shown in fig. 1 and 2, a stud 23 may be disposed on the convex surface 21 of the base 2, and the detachable connection manner of the vibration sensor 1 and the base 2 may be implemented through a threaded connection manner; in another embodiment, the vibration sensor 1 may also be connected to the convex surface 21 of the base 2 by means of a snap-fit connection; in a further embodiment, the vibration sensor 1 may also be attached to the convex surface 21 of the base 2 by clamping.

Second, the vibration sensor 1 of the present application may be a wired type (for example, the structure shown in fig. 1, the vibration sensor 1 includes the data line 11) or a wireless type, and the type of the vibration sensor 1 is not particularly limited in the present application. In addition, since the vibration sensor 1 of the present application is an electronic device widely used in the related art, the detailed working process and working principle thereof will not be repeated.
